T'IP .FOR ATOMIZERS AND NEBULIZERS.

SPECIFICATION forming part of Letters Patent No. 692,798, dated February4, 1902.

Application iilecl Getober 29, 1900. Serial No. 34,764. (No model.)

T0 @ZZ whom it may concern:

Be it known that I, CYRUS J. SELTZER, of Philadelphia, county ofPhiladelphia, and State of Pennsylvania, have invented a new and usefulImprovement in Tips for Atomizers and Nebulizers, of which the followingis a specification.

My invention relates to an improvement in tips for atomizers andnebnlizers; and it consists in the parts and combinations hereindescribed and claimed.

l Referring now to the drawings forming a part of this application, andin which similar reference-letters designate corresponding parts in theseveral views, Figure 1 repre-- sents one form of my invention. Fig. 2illustrates a modification thereof. Fig. 3 shows a fnrthermodication ofmyinvention. Fig.4

is a sect-ion taken on the line a; of Fig. 3.

My invention is intended for use with com- T bined atomizers andnebulizers,such as shown in my Patent No. 638,481, dated December 5,1899.

Since my invention relates solely to an improvement in the tip and thecoperating ends of the inner and outer atomizer-tubes, I will confine mydescription and drawings to such tip and its cooperating parts,referring to my above patent, No. 638,481, for a full disclosure of thetype of apparatus for which my improvement is adapted.

Heretofore in the use of combined atomizers and nebulizers it has beennecessary to remove the atomizer-tip when employing the apparatus as anebulizer. The liability of misplacing or losing the tip when removedand the failure to always properly adjust the tip when replacing it inposition have rendered such construction undesirable.

The object of my invention is to overcome such defects and to obtain asimpler structure which will be less apt to become deranged.

Referring now especially to Fig. l, A is the inner atomizer-tube,provided with a bore C. B is the outer atomiZer-tube. D is atip havingan aperture Gr, whichis shaped to fit snugly against or around the outersurface of inner tube A. E is an enlargement of the 5o bore C, and F Fare perforations through the walls of the inner tube C. The tube C maybe provided with only one perforation'E it' desired. While I have shownthe bore C provided with an enlargement E, satisfactory results can beobtained by properly proportion-4 ing said bore C and maintaining it ofuniform size throughout the tube A. The tip D is adjustably secured tothe tube Bin any desired:

manner, screw-threads N being shown for this purpose in the drawings.The aperture G inY the tip D is ot'` such size that when said tip isadjusted in its outward position (shown by broken lines in the drawings)the air can escape therethrough from the outer tubeB with suficientfreedom to prevent-the atomizer action of the apparatus, the resultbeing similar to that obtained by entirely removing the atomizer-tipinthe apparatus of my above patent, No. 638,481. As shown in Fig. 1, thetube A is so proportioned that it completely closes the aperture G whenthe tip D is adj usted in its inward position.

When using the combined .atomizer and nebulizergas an atomizer, the tipD is adj usted in its inner position, as shown by full lines in thedrawings. Air under pressure is then admitted to the apparatus in anyusual manner,

as illustrated in my above patent, No. 638,481.

The liquid to be atomized is forced up through the bore C by thepressure of the air, and a portion of the air passing from the outertubeV B through perforations F mingles with the liquid issuing from thebore C and atomizes it. The end portion of tube A,'having theperforations F, thus constitutes an atomizing-tip. Vhen it is desired touse the com-V bined atomizer and nebulizer as a nebulizer,5

the tip is adjusted in its outer position, as l shown by broken lines inthe drawings. Air under pressure is then admitted to the apparatusthrough the nebulizer-tube in any preferred manner-as illustrated, forexample, in n IOG end of the outer tube when the atomizer-tip had beenremoved in the previous types of combined atomizers and nebulizers.

In the modification shown in Fig. 2 the in ner atomizertube A isprovided with a reduced portion J and has secured thereto arelativelysmall atomizing-tip H, which is provided with a perforation I.The air for atomizing the liquid issuing through the bore C passes fromthe outer tube B through the perforation I and mingles with the liquidin the tip II, the tip D being, of course, adjustedin its inner positionwhen the apparatus is so operating as an atomizer. When the apparatus isto be used as a nebulizer, the tip D is adjusted in its outer position,"(shown by broken lnes,) and the action is exactly similar to thatdescribed in reference to Fig. 1.

In the construction illustrated in Figs. 3 and 4 the inner tube A isprovided With a reduced portion L and has a relatively smallatomizing-tip K secured thereto, the tip K eX- tending along only aportion of such reduced portion Land being secured to the inner tube atthe surfaces O. (See especially Fig. 4.) The air for atomizing theliquid issuing through the bore C passes from the outer tube B throughthe openings M, which are formed by the inner end of the tip K and thereduced portion L of tube A, and mingles with the liquidin said smalltip K. It is understood that when so using the apparatus as an atomizerthe tip D is adjusted in its inner position, as shown by full lines inFig. 3. When it is desired to use the apparatus as a nebulizer, the tipD is adjusted in its out- Ward position, (shown by broken lines in Fig.3,) and the operation is similar to that described in reference to Figs.1 and 2.

It is obvious that many changes could be made in the proportions andarrangements of the elements without in any Way departing from thespirit and scope of my invention.

I-Iaving thus described my invention, what Iclaim as new, and desire tosecure byLetters Patent, is

1. In a combined atomiz'er and nebuliz'cr and in combination with theusual inner and outer atomizer-tubes thereof, an atomizingtip carried bysaid inner tube and provided with passages for air and liquid, saidpassages being arranged to cause the air to impinge upon the issuingliquid and thereby atomize said liquid in lthe usual manner, and anapertured tip adj ustably secured to said outer tube.

2. In a combined atomizer and nebulizer and in combination With theusual inner and outer atomizer-tubes thereof, an atomizing tip carriedby said inner atomizer-tube, and provided with passages for air andliquid, said passages being arranged to cause the air to impinge uponthe issuing liquid and thereby atomize said liquid in the usual manner,and an apertured lip adjustably secured to said outer tube and soconstructed that when adjusted in one position its aperture will snuglyfit against or around the outer surface of said atomizing-tip, whilewhen adjusted in another position its aperture will permit free escapeof air therethrough from said outer tube, substantially as described.

In testimony whereof I hereunto set my hand, this 25th day of October,1900, in thc presence of two attesting Witnesses.
